62-year-old man with history of oropharyngeal cancer, treated by chemoradiation therapy. Contrast-enhanced multiphase DECT of chest performed for surgical planning. Axial image from iodine concentration map, reconstructed from equilibrium-phase acquisition, shows thin ringlike peripheral high iodine concentration, involving nodule’s entire circumference. Nodule underwent resection, revealing oropharyngeal carcinoma metastasis. Case represents true-positive example of using ringlike peripheral high iodine co

Metastasis was treated by upfront microwave ablation (MWA) and adjuvant systemic therapy (six cycles of FOLFIRI plus Bevacizumab). A. Axial contrast-enhanced T1-weighted MR image obtained before treatment shows 32x29x37-mm target lesion in segment V (arrow). B. Ultrasound image obtained during ultrasound-guided MWA shows hyperechogenicity around target lesion, corresponding with heat energy from ablation antennas. C. Axial contrast-enhanced T1-weighted MR image obtained 1 month after MWA shows 56x49x52-mm r
